CAN (control area network) is a standardized system for multiplex-communication. Multiplex communication means that several control modules can use the same cables for communication without traffic from one control module interfering with traffic from another.
Volvo has developed a new standard for multiplex communication - VOLCANO. VOLCANO is a development of CAN and uses real time operation and prioritization. The description of prioritization is based on VOLCANO but is designated CAN.
The control area network (CAN) standard specifies:
- That two cables are to be used (CAN H and CAN L)
- What voltage levels must be used
- What a message should look like
- How transmission errors should be handled.
